False.
Arteries are said to be more muscular.
That means Arteries ARE* MUSCLES
Answer:
201.73g
Explanation:
From the chemical reaction above, it can be seen that 3 moles of hydrogen yielded 2 moles of ammonia.
Now, 17.8 moles of hydrogen will yield a certain number of moles of ammonia. To get this certain number of moles: we have (17.8 * 2)/3 = 11.87 moles
Hence, 17.8 moles of hydrogen will produce 11.87 moles of ammonia. Now, we proceed to calculate the mass of ammonia produced.
The mass of ammonia produced is the molar mass of ammonia multiplied by the number of moles of ammonia.
The molar mass of ammonia is 14 +3(1) = 17g/mol
Now the mass produced is thus 17 * 11.87 = 201.73g
Bohr's
Explanation:
Experimental evidence of Rutherford best supports the Bohr's model of the atom.
Rutherford performed the gold foil experiment in which he bombarded thin gold foil with alpha particles. He found that most of the particles passed through with just few bouncing back.
With this knowledge, he proposed the nuclear model of the atom. The model suggests that an atom is made up of a positively charge dense center and a large space outside where electrons revolves.
- The Bohr's model of the atom was based on quantum mechanics proposed by Planck.
- He assumed the Rutherford's model and suggested that the extranuclear space is made up of electrons in spherical orbits around the nucleus.

<span>CCl4 is a non polar molecule because though each of the C-Cl bond is polar but the resultant of all these dipole moments is zero as its a symmetrical tetrahedral shape molecule ,and their is a cancellation of dipole moment in each pair.</span>
